The conversion factor from kilograms to grams is 1000, which means that 1 kilogram is equal to 1000 grams:

1 kg = 1000 g

To convert 400.8 kilograms into grams we have to multiply 400.8 by the conversion factor in order to get the mass amount from kilograms to grams. We can also form a simple proportion to calculate the result:

1 kg → 1000 g

400.8 kg → M_(g)

Solve the above proportion to obtain the mass M in grams:

M_(g) = 400.8 kg × 1000 g

M_(g) = 400800 g

The final result is:

400.8 kg → 400800 g

We conclude that 400.8 kilograms is equivalent to 400800 grams:
